quick question about coconut milk

I just received the primal recipe book and was wondering...can one substitute almond milk for coconut milk straight up or could there possibly be some changes in consistency/cooking/etc in certain recipes?

I tried to search for it in the forum, but I had trouble locating a definitive answer.

And-- since you buy almond milk-- its worth mentioning that 'coconut milk' for recipes is a can, used for cooking, and NOT the 'coconut beverage' made by So Delicious that can be found often near the almond milk!
